Building a multicultural peer-consultation team: Planning, implementing, and early sustainment evaluation

This article represents an implementation-focused evaluation of a multicultural peer-consultation team situated within a psychiatry department in a large academic medical center in the Southern United States. The evaluation comprised anonymous self-report questionnaires (n = 14) as well as individual (n = 3) or group interviews (n = 10) conducted by outside independent evaluators. Participants were current and former team members (i.e., graduate trainees, mental health care providers, clinical and research staff members) who voluntarily participated in this multimethod implementation evaluation. Results indicated that attendance on the team had several important impacts on members, and most notably an increased ability to provide multiculturally competent care, that is treatment that carefully and routinely considers the influence of culture and context on patients and therefore their clinical presentation. Further, no negative impacts from participating on the team were noted. A primary strength of the team's sustainability is that participation on the team was deemed to be relevant and useful by current and former team members. A major barrier to participation on the team is competing demands, such as high clinical loads. We conclude that this model for multicultural peer-consultation holds promise as an effective and implementable educational method for mental health care professionals. We discuss strengths, limitations, and future directions for research.

Phenotyping misophonia: Psychiatric disorders and medical health correlates

Misophonia is characterized by decreased tolerance to specific sounds and associated stimuli that causes significant psychological distress and impairment in daily functioning (Swedo et al., 2022). Aversive stimuli (often called “triggers”) are commonly repetitive facial (e.g., nose whistling, sniffling, and throat clearing) or oral (e.g., eating, drinking, and mouth breathing) sounds produced by other humans. Few empirical studies examining the nature and features of misophonia have used clinician-rated structured diagnostic interviews, and none have examined the relationship between misophonia and psychiatric disorders in the Diagnostic and Statistical Manual-5th version (DSM-5; American Psychiatric Association, 2013). In addition, little is known about whether there are any medical health problems associated with misophonia. Accordingly, the purpose of the present study was to improve the phenotypic characterization of misophonia by investigating the psychiatric and medical health correlates of this newly defined disorder. Structured diagnostic interviews were used to assess rates of lifetime and current DSM-5 psychiatric disorders in a community sample of 207 adults. The three most commonly diagnosed current psychiatric disorders were: (1) social anxiety disorder, (2) generalized anxiety disorder, and (3) specific phobia. The three most common lifetime psychiatric disorders were major depressive disorder, social anxiety disorder, and generalized anxiety disorder. A series of multiple regression analyses indicated that, among psychiatric disorders that were correlated with misophonia, those that remained significant predictors of misophonia severity after controlling for age and sex were borderline personality disorder, obsessive compulsive disorder, and panic disorder. No medical health problems were significantly positively correlated with misophonia severity.

ENaC activation by proteases

Proteases are fundamental for a plethora of biological processes, including signalling and tissue remodelling, and dysregulated proteolytic activity can result in pathogenesis. In this review, we focus on a subclass of membrane‐bound and soluble proteases that are defined as channel‐activating proteases (CAPs), since they induce Na⁺ ion transport through an autocrine mechanism when co‐expressed with the highly amiloride‐sensitive epithelial sodium channel (ENaC) in Xenopus oocytes. These experiments first identified CAP1 (channel‐activating protease 1, prostasin) followed by CAP2 (channel‐activating protease 2, TMPRSS4) and CAP3 (channel‐activating protease 3, matriptase) as in vitro mediators of ENaC current. Since then, more serine‐, cysteine‐ and metalloproteases were confirmed as in vitro CAPs that potentially cleave and regulate ENaC, and thus this nomenclature was not further followed, but is accepted as functional term or alias. The precise mechanism of ENaC modulation by proteases has not been fully elucidated. Studies in organ‐specific protease knockout models revealed evidence for their role in increasing ENaC activity, although the proteases responsible for ENaC activation are yet to be identified. We summarize recent findings in animal models of these CAPs with respect to their implication in ENaC activation. We discuss the consequences of dysregulated CAPs underlying epithelial phenotypes in pathophysiological conditions, and the role of selected protease inhibitors. We believe that these proteases may present interesting therapeutic targets for diseases with aberrant sodium homoeostasis.

Examining emotional functioning in misophonia: The role of affective instability and difficulties with emotion regulation

Misophonia is a newly described condition characterized by sensory and emotional reactivity (e.g., anxiety, anger, disgust) to repetitive, pattern-based sounds (e.g., throat clearing, chewing, slurping). Individuals with misophonia report significant functional impairment and interpersonal distress. Growing research indicates ineffective coping and emotional functioning broadly (e.g., affective lability, difficulties with emotion regulation) are central to the clinical presentation and severity of misophonia. Preliminary evidence suggests an association between negative emotionality and deficits in emotion regulation in misophonia. Still, little is known about (a) the relationships among specific components of emotional functioning (e.g., emotion regulation, affective lability) with misophonia, and (b) which component(s) of misophonia (e.g., noise frequency, emotional and behavioral responses, impairment) are associated with emotional functioning. Further, despite evidence that mood and anxiety disorders co-occur with misophonia, investigation thus far has not controlled for depression and anxiety symptoms. Examination of these relationships will help inform treatment development for misophonia. The present study begins to disambiguate the relationships among affective lability, difficulties with emotion regulation, and components of misophonia. A sample of 297 participants completed questionnaires assessing misophonia, emotional functioning, depression, anxiety, and COVID-19 impact. Findings indicated that misophonia severity was positively associated with each of these constructs with small to medium effect sizes. When controlling for depression, anxiety, and COVID-19 impact, results from this preliminary study suggest that (a) difficulties with emotion regulation may be correlated with misophonia severity, and (b) misophonic responses, not number of triggers or perceived severity, are associated with difficulties with emotion regulation. Overall, these findings begin to suggest that emotion regulation is important to our understanding the risk factors and treatment targets for misophonia.

A Mobile App to Enhance Behavioral Activation Treatment for Substance Use Disorder: App Design, Use, and Integration Into Treatment in the Context of a Randomized Controlled Trial

Background

Group-based formats typically used in low-resource substance use disorder (SUD) treatment settings result in little individual attention to help reinforce and guide skill use, which may contribute to poor posttreatment outcomes. Smartphone apps offer a convenient, user-friendly, and cost-effective tool that can extend the reach of effective SUD treatments. A smartphone app was developed and integrated into a group-based, brief behavioral activation (BA) treatment for SUD to increase engagement in treatment skills outside clinician-administered sessions.

Objective

This study aims to describe the features of the app and its use and integration into treatment, report the participants’ self-reported feasibility and acceptability of the app, and discuss challenges and provide recommendations for future smartphone app integration into behavioral treatments for SUD.

Methods

A total of 56 individuals recruited from intensive outpatient SUD treatment received a smartphone-enhanced BA treatment, the Life Enhancement Treatment for Substance Use. Self-reported weekly app use and reasons for nonuse were assessed at posttreatment and at 1- and 3-month follow-ups. In addition, 2-tailed t tests and chi-square tests compared the self-reported use of each app component and overall app use over time.

Results

Participant feedback suggested that the integration of the smartphone app into the Life Enhancement Treatment for Substance Use was feasible and well accepted, and participants found the app useful for planning value-based activities outside of sessions. Self-reported app engagement decreased over the follow-up period: 72% (39/54) of participants reported using the app at posttreatment, decreasing to 69% (37/54) at the 1-month follow-up and 37% (20/54) at the 3-month follow-up. Participants reported forgetting to use the app as a primary reason for nonuse.

Conclusions

This study provides support for the feasibility and acceptability of smartphone-enhanced BA treatment, offering promise for future research testing the integration of technology into SUD treatment. Design decisions may help streamline smartphone integration into treatment, for example, allowing participants to download the treatment app on their own phones or use a low-cost study smartphone (or offering both options). Long-term app engagement may be increased via built-in reminders, alerts, and in-app messages.

Genome-wide Gene-by-Sex Interaction Studies Identify Novel Nonsyndromic Orofacial Clefts Risk Locus

Risk loci identified through genome-wide association studies have explained about 25% of the phenotypic variations in nonsyndromic orofacial clefts (nsOFCs) on the liability scale. Despite the notable sex differences in the incidences of the different cleft types, investigation of loci for sex-specific effects has been understudied. To explore the sex-specific effects in genetic etiology of nsOFCs, we conducted a genome-wide gene × sex (GxSex) interaction study in a sub-Saharan African orofacial cleft cohort. The sample included 1,019 nonsyndromic orofacial cleft cases (814 cleft lip with or without cleft palate and 205 cleft palate only) and 2,159 controls recruited from 3 sites (Ethiopia, Ghana, and Nigeria). An additive logistic model was used to examine the joint effects of the genotype and GxSex interaction. Furthermore, we examined loci with suggestive significance (P < 1E-5) in the additive model for the effect of the GxSex interaction only. We identified a novel risk locus on chromosome 8p22 with genome-wide significant joint and GxSex interaction effects (rs2720555, p_2df = 1.16E-08, p_GxSex = 1.49E-09, odds ratio [OR] = 0.44, 95% CI = 0.34 to 0.57). For males, the risk of cleft lip with or without cleft palate at this locus decreases with additional copies of the minor allele (p < 0.0001, OR = 0.60, 95% CI = 0.48 to 0.74), but the effect is reversed for females (p = 0.0004, OR = 1.36, 95% CI = 1.15 to 1.60). We replicated the female-specific effect of this locus in an independent cohort (p = 0.037, OR = 1.30, 95% CI = 1.02 to 1.65), but no significant effect was found for the males (p = 0.29, OR = 0.86, 95% CI = 0.65 to 1.14). This locus is in topologically associating domain with craniofacially expressed and enriched genes during embryonic development. Rare coding mutations of some of these genes were identified in nsOFC cohorts through whole exome sequencing analysis. Our study is additional proof that genome-wide GxSex interaction analysis provides an opportunity for novel findings of loci and genes that contribute to the risk of nsOFCs.

Development and Initial Validation of the Duke Misophonia Questionnaire

Misophonia is characterized by decreased tolerance and accompanying defensive motivational system responding to certain aversive sounds and contextual cues associated with such stimuli, typically repetitive oral (e. g., eating sounds) or nasal (e.g., breathing sounds) stimuli. Responses elicit significant psychological distress and impairment in functioning, and include acute increases in (a) negative affect (e.g., anger, anxiety, and disgust), (b) physiological arousal (e.g., sympathetic nervous system activation), and (c) overt behavior (e.g., escape behavior and verbal aggression toward individuals generating triggers). A major barrier to research and treatment of misophonia is the lack of rigorously validated assessment measures. As such, the primary purpose of this study was to develop and psychometrically validate a self-report measure of misophonia, the Duke Misophonia Questionnaire (DMQ). There were two phases of measure development. In Phase 1, items were generated and iteratively refined from a combination of the scientific literature and qualitative feedback from misophonia sufferers, their family members, and professional experts. In Phase 2, a large community sample of adults (n = 424) completed DMQ candidate items and other measures needed for psychometric analyses. A series of iterative analytic procedures (e.g., factor analyses and IRT) were used to derive final DMQ items and scales. The final DMQ has 86 items and includes subscales: (1) Trigger frequency (16 items), (2) Affective Responses (5 items), (3) Physiological Responses (8 items), (4) Cognitive Responses (10 items), (5) Coping Before (6 items), (6) Coping During (10 items), (7) Coping After (5 items), (8) Impairment (12 items), and Beliefs (14 items). Composite scales were derived for overall Symptom Severity (combined Affective, Physiological, and Cognitive subscales) and Coping (combined the three Coping subscales). Depending on the needs of researchers or clinicians, the DMQ may be use in full form, individual subscales, or with the derived composite scales.

A Preliminary Investigation of the Association Between Misophonia and Symptoms of Psychopathology and Personality Disorders

Misophonia is a condition characterized by defensive motivational system emotional responding to repetitive and personally relevant sounds (e.g., eating, sniffing). Preliminary research suggests misophonia may be associated with a range of psychiatric disorders, including personality disorders. However, very little research has used clinician-rated psychometrically validated diagnostic interviews when assessing the relationship between misophonia and psychopathology. The purpose of this study was to extend the early research in this area by examining the relationship between symptoms of misophonia and psychiatric diagnoses in a sample of community adults, using semi-structured diagnostic interviews. Results indicated higher misophonia symptoms were associated with more clinician-rated symptoms of personality disorders, but not other disorders. Anxiety partially mediated the relationship between personality disorder symptoms and misophonia. These results suggest misophonia may be associated with a range of psychiatric symptoms and highlight the role of anxiety in this poorly understood condition.

Feasibility, acceptability and future adaptation of the Chinese translated Behavioural activation (C-BA) treatment for depression: A pilot study

BACKGROUND

Although depression is prevalent among Chinese international students (CIS), only 4% of CIS seek treatment. Behavioural activation (BA) has been suggested as a culturally sensitive treatment for depression that has the potential to meet the clinical needs of CIS. The current pilot study tested the feasibility, acceptability and themes for future cultural adaptations of a Chinese translated BA treatment (C-BA) among CIS.

METHODS

Six CIS with elevated depressive symptoms (Beck Depression Inventory, BDI ≥ 14) completed a six-session individual C-BA treatment and assessments at pre- and post-treatment and a 1-month follow-up. Primary outcome measures included treatment feasibility, acceptability and qualitative interview data informing future adaption of C-BA. Exploratory analyses examined group changes in depressive symptoms over time and clinically significant symptom changes on individual levels.

RESULTS

All participants found the treatment to be highly feasible and culturally acceptable, and were highly engaged in the treatment. Themes of future cultural adaptions were generated from the qualitative interviews. Significant decreases in depressive symptoms were observed at a one1-month post-treatment follow-up assessment.

CONCLUSIONS

Preliminary evidence suggests that C-BA has the potential to be a culturally sensitive treatment for depression among CIS. CIS demonstrated openness to psychotherapy and high treatment engagement.

Evaluating Differential Item Functioning (DIF) of the Chinese Version of the Behavioral Activation for Depression Scale (C-BADS)

Abstract. Depression is prevalent in both China and Taiwan, and Behavioral Activation (BA), an Evidence-Based Treatment (EBT) for depression, is ideally suited for cross cultural implementation. As a first step, the current study examined cross cultural differences in the understanding of BA constructs, by investigating item level differences in functioning between the English and Chinese versions of Behavioral Activation for Depression Scale (BADS and C-BADS; Kanter, Mulick, Busch, Berlin, & Martell, 2007 ; Li, Ding, Kanter, Zeng, & Yang, 2014) . 752 college students were recruited from China, Taiwan, and the United States. Factorial invariance-based Differential Item Functioning (DIF) analysis was used to study item level differences in functioning for the BADS and C-BADS. Results. DIF was observed in the majority of BADS items, with items in the avoidance and impairment factors showing the greatest DIF. The constructs of avoidance and impairment demonstrate less cross-cultural generalizability compared to the activation construct. Suggestions for the implementation of DIF analysis for future cross cultural psychometric studies, and further modification of the C-BADS as a clinical assessment tool in China and Taiwan, are discussed.

The Mediating Role of Emotion Regulation Within the Relationship Between Neuroticism and Misophonia: A Preliminary Investigation

Misophonia is a newly described condition characterized by heightened emotional reactivity (e.g., anger, anxiety, and disgust) to common repetitive sounds (e.g., oral or nasal sounds made by others), accompanied by difficulties responding to these sounds (e.g., intolerance, avoidance, and escape) and associated impairment in functioning. Although research indicates that problematic emotional responses are a key characteristic of misophonia, it is unknown whether individual differences in experiencing and regulating emotional responses influence severity of misophonia symptoms. Examination of individual differences in emotional functioning will help to guide treatment development for misophonia. Accordingly, the present study examined the associations among trait neuroticism, difficulties with emotion regulation, and symptoms of misophonia. For this study, a sample of 49 adults completed the Difficulties with Emotion Regulation Scale, the Misophonia Questionnaire, and the neuroticism subscale of the NEO-Personality inventory. Findings indicated that difficulties with emotion regulation and neuroticism were significantly positively correlated with symptoms of misophonia. Bootstrapped mediation analyses suggested that difficulties controlling impulsive behavior while experiencing intense negative emotions fully mediated the relationship between neuroticism and symptoms of misophonia. Results from this study suggest that neuroticism and difficulties with emotion regulation may be important risk factors and treatment targets for adults with misophonia, and difficulties controlling impulsive behavior when distressed may be an important individual difference accounting for the relationship between neuroticism and misophonia.

A Path From Childhood Sensory Processing Disorder to Anxiety Disorders: The Mediating Role of Emotion Dysregulation and Adult Sensory Processing Disorder Symptoms

Although maladaptive sensory processing has been observed among individuals with persistent heightened anxiety, it is unclear if difficulties processing sensory input early in life lead to anxiety disorders in adulthood and what mechanisms would drive this progression. In a transdiagnostic clinical sample of 231 adults characterized by heightened difficulties with emotion regulation, the present study sought to examine whether: (a) childhood sensory processing disorder (SPD) symptoms predict an increased probability of an anxiety disorder diagnosis in adulthood; and (b) difficulties with emotion regulation and adult SPD symptoms mediate this relationship. Participants were administered the Structured Clinical Interview for Axis-I disorders and self-reported symptoms of SPD experienced in childhood and adulthood. Results suggested that childhood SPD symptoms were significantly associated with a higher likelihood of a lifetime anxiety disorder diagnosis. Difficulties with emotion regulation fully mediated the relationship between childhood SPD and (a) any anxiety disorder in adulthood and, specifically (b) current generalized anxiety disorder (GAD). Further, we found evidence for a candidate model accounting for the relationship among childhood SPD, adulthood SPD, difficulties with emotion regulation, and anxiety disorders in adulthood. Specifically, our data indicated that high symptoms of SPD in childhood may lead to high SPD symptoms in adulthood, which then lead to high emotion dysregulation, ultimately conferring vulnerability for an anxiety disorder diagnosis. Taken together, these findings provide preliminary evidence for how sensory processing impairments in childhood may relate to anxiety through difficulties regulating emotion regulation.

Distress tolerance trajectories following substance use treatment

OBJECTIVE

Distress tolerance (DT), the ability to withstand aversive internal states, represents an important risk factor for substance use relapse and a potential treatment target. Neurobiological research in substance using populations suggests that continued substance use could erode DT, whereas abstinence could bolster it. The current study characterized trajectories of behavioral and self-reported indices of DT and examined the prospective effect of substance use on DT trajectories among those seeking treatment for substance use.

METHOD

Individuals (N = 263, Mage = 42.68, SD = 11.8, 70.7% male, 94.7% African American) in residential substance use treatment completed subjective (Distress Tolerance Scale) and behavioral (Mirror Tracing Persistence Task-computerized version) DT measures, as well as report of daily substance use (timeline follow-back) over 5 assessment time-points from pretreatment to 12 months posttreatment. Latent curve modeling estimated DT trajectories and their associations with substance use behavior, including abstinence duration (days until first use) and substance use frequency (percentage of substance use days between assessments).

RESULTS

Self-reported and behavioral DT indicators both exhibited positive, nonlinear change over time (standardized slope parameter estimates: Distress Tolerance Scale β = 0.61, p < .01; Mirror Tracing Persistence Task β = 0.34, p < .01). Abstinence duration was associated with greater improvement in behavioral (β = .20, p = .03) DT specifically. Frequency of use was statistically significantly associated with attenuated behavioral DT at 6-month (β = -.12, p = .03) and 12-month follow-ups (β = -.08, p = .045).

CONCLUSIONS

DT appears to improve appreciably posttreatment, and return to substance use may shape the degree of this improvement. Collectively, these findings support the conceptualization of DT as a malleable treatment target and emphasize the benefit of abstinence on improvement in DT.

Substance type moderates the longitudinal association between depression and substance use from pre-treatment through a 1-year follow-up

BACKGROUND

Research examining directionality of the relationship between depressive symptoms and substance use following treatment entry is limited. Furthermore, substances differ in their neurobiological effects on mood. The relationship between depression and substance use following treatment entry may be moderated by dependence on specific substances. The study tested (a) lagged effects between depressive symptoms and substance use frequency following substance use treatment entry through a 1-year post-treatment follow-up and (b) if substance dependence type moderates these effects.

METHODS

Participants (N = 263) entering residential treatment were assessed for DSM-IV substance dependence, depressive symptoms (Beck Depression Inventory), and percentage of substance use days at post-treatment, 1-, 3-, 6- and 12-month follow-up assessments (time t₀ to t₄). Linear mixed effects models tested lagged effects between depressive symptoms and substance use frequency and the impact of substance type (i.e., dependence on alcohol, cannabis, opioid, cocaine, hallucinogen/PCP) on this relationship.

RESULTS

After controlling for concurrent effects, substance type moderated each longitudinal relationship. Depressive symptoms significantly predicted substance use frequency at the subsequent follow-up assessment, only among individuals with pre-treatment opioid dependence (B = 5.55, SE = 0.89, z = 6.21, p < 0.01). Substance use frequency significantly predicted depressive symptoms at the subsequent follow-up assessment, but not among individuals with cannabis dependence at pre-treatment (B = 1.01, SE = 0.22, t (524) = 4.49, p < 0.01).

CONCLUSIONS

The directionality of depression-substance use comorbidity may differ based on the substance of dependence at pre-treatment. Opioid users may especially benefit from treating both depression and substance use.

Nanoconjugation of bicistronic DNA vaccine against Edwardsiella tarda using chitosan nanoparticles: Evaluation of its protective efficacy and immune modulatory effects in Labeo rohita vaccinated by different delivery routes

DNA-based immunization has proven to be an effective prophylactic measure to control aquatic animal diseases. In order to improve the efficiency of vaccine against fish pathogen, novel delivery mechanism needs to be adopted. In the present study we nanoconjugated the previously constructed DNA vaccine (pGPD + IFN) with chitosan nanoparticles (CNPs) by complex coacervation process. After construction of the vaccine, an in vivo vaccination trial was conducted in which 2 groups of rohu (L. rohita) fingerlings were vaccinated with CNPs-pGPD + IFN, one group by oral route (incorporated in feed for 14 days) and the other by immersion route (primary and booster immunised), whereas, a third group was intramuscularly (I/M) injected (initial and booster immunised) with naked pGPD + IFN and subsequently challenged with E. tarda (8.7 × 10⁴ CFU/fish) at 35-day post initial vaccination. The protective immune responses were determined in terms of relative percentage survival (RPS), specific antibody production, non-specific immune response, expression kinetics of immune-related genes and pathological manifestation. Evaluation of RPS analysis revealed that CNPs-pGPD + IFN groups recorded highest RPS (81.82% and 72.73% in oral and immersion vaccinated fish group respectively) while the naked pGPD + IFN injected group showed 63.62% RPS when compared with 55% cumulative mortality of control group. In addition, NBT, myeloperoxidase activity, serum lysozyme activity and specific antibody titre in case of CNPs-pGPD + IFN groups showed higher activities during all the time points. Furthermore, CNPs-pGPD + IFN groups showed significant (p < 0.05) upregulation of different immune gene transcripts (IgHC, iNOS, TLR22, NOD1 and IL-1β) in three immunologically important tissues post immunization (both primary and booster dose) as well as after challenge. Thus, from this study, we can conclude that oral or immersion vaccination with CNPs-pGPD + IFN can orchestrate an effective immunisation strategy in organizing a coordinative immune response against E. tarda in L. rohita exhibiting minimum stress to the host with maximum efficacy.

The effect of a behavioral activation treatment for substance use on post-treatment abstinence: a randomized controlled trial

AIMS

To compare outcomes for a behavioral activation group treatment for substance use [life enhancement treatment for substance use (LETS ACT)] versus a time and group size-matched control condition delivered in a residential treatment setting.

DESIGN

Single-site two-arm parallel-group randomized clinical trial with follow-up assessment at 3, 6 and 12 months post-treatment.

SETTING

Residential substance use treatment facility in the United States.

PARTICIPANTS

Participants were 263 adults [mean age 42.7 (11.8); 29.5% female; 95.4% African American; 73.2% court mandated] whose insurance dictated 30-day (65.9%) or 90-day (34.1%) treatment duration.

INTERVENTION AND COMPARATOR

LETS ACT (n = 142) is a treatment developed originally for depression and modified for substance use. It teaches participants to increase positively reinforcing value-driven activities in order to counter depression and relapse. The control group [supportive counseling (SC); n = 121] received time and group size-matched supportive counseling. Treatment was delivered in five or eight 1-hour sessions depending on patient length of stay.

MEASUREMENTS

Percentage abstinent at follow-up, percentage of substance use days among those reporting use, depressive symptoms [Beck Depression Inventory (BDI)] and adverse consequences of drug use [Short Inventory of Problems-Alcohol and Drug (SIP-AD)].

FINDINGS

LETS ACT had significantly higher abstinence rates at 3 months [odds ratio (OR) = 2.2, 95% confidence interval (CI) = 1.3-3.7], 6 months (OR = 2.6, 95% CI= 1.3-5.0) and 12 months (OR = 2.9, 95% CI = 1.3-6.1) post-treatment compared with SC. LETS ACT participants reported significantly fewer adverse consequences from substance use at 12 months post-treatment [B = 4.50, standard error (SE) = 2.17, 95% CI = 0.22-8.78]. Treatment condition had no effect on percentage substance use days among those who resumed use or on change in depressive symptoms; the latter decreased over time only in those who remained abstinent after residential treatment irrespective of condition (B = 0.43, SE = 0.11, 95% confidence interval = 0.22-0.65).

CONCLUSIONS

A behavioral activation group treatment for substance use (LETS ACT) appears to increase the likelihood of abstinence and reduce adverse consequences from substance use up to 12 months post-treatment.

Bite Force Assessment of Mandibular Interforaminal Fractures Treated with Combination of Microplate and Miniplate—A Randomized Control Study

The purpose of this study was to compare the mechanical behavior of combination of microplate and miniplate with two standard miniplates for fixation of mandibular fractures in the interforaminal region on the basis of bite force and other clinical parameters. A prospective randomized study was conducted on 20 patients with mandibular fracture requiring open reduction and internal fixation (ORIF) who were randomly categorized into Group A and Group B with 10 patients in each group. Ten healthy persons whose age and gender matched with study groups were included in control Group C. Pre- and postoperative bite force was measured at specified intervals in both the study groups and was compared with the control group. The bite force values were comparatively less in Group A than Group B, although there was no statistically significant difference. Also, bite force values were less in both the study groups when compared with the control group. No statistically significant difference was found in other clinical parameters such as infection, fracture mobility, and hardware failure. The results were suggestive that the use of microplate and miniplate combination in management of minimally displaced mandibular fractures in the interforaminal region provides stable fixation comparable to two miniplate combination.

Emotion differentiation predicts likelihood of initial lapse following substance use treatment

BACKGROUND

An estimated 40% to 70% of individuals treated for a substance use disorder relapse within one year following treatment (Walitzer and Dearing, 2006). Relapse is often driven by the need to cope with intense negative affect (Koob, 2013). Emotion differentiation, defined as the ability to distinguish among various emotion states, has been linked to better behavioral control in the face of negative affect (Kashdan et al., 2015). The aim of the current study was to determine if higher levels of emotion differentiation are associated with the risk of experiencing an initial lapse following entry into residential substance use treatment.

METHODS

A total of 213 substance users (69.5% male, 94.4% African American, M age=43.01±11.35years) entering residential treatment were assessed on study variables at pre- and post-treatment, and at 1-, 3-, 6- and 12-month post-treatment. Emotion differentiation was calculated using ratings on five negative affect items derived from the Positive and Negative Affect Schedule (PANAS; Watson et al., 1988) at five assessment points.

RESULTS

A Cox proportional-hazards regression model adjusting for age and negative affect intensity demonstrates that for every unit increase in emotion differentiation, there is a 27% reduction in the likelihood of initial lapse on any given day (OR=0.73; 95% CIs [0.56, 0.95]).

CONCLUSIONS

The ability to differentiate among negative emotion states protects against initial lapse following treatment.

DNA double-strand break repair in Penaeus monodon is predominantly dependent on homologous recombination

DNA double-strand breaks (DSBs) are mostly repaired by nonhomologous end joining (NHEJ) and homologous recombination (HR) in higher eukaryotes. In contrast, HR-mediated DSB repair is the major double-strand break repair pathway in lower order organisms such as bacteria and yeast. Penaeus monodon, commonly known as black tiger shrimp, is one of the economically important crustaceans facing large-scale mortality due to exposure to infectious diseases. The animals can also get exposed to chemical mutagens under the culture conditions as well as in wild. Although DSB repair mechanisms have been described in mammals and some invertebrates, its mechanism is unknown in the shrimp species. In the present study, we show that HR-mediated DSB repair is the predominant mode of repair in P. monodon. Robust repair was observed at a temperature of 30 °C, when 2 µg of cell-free extract derived from hepatopancreas was used for the study. Although HR occurred through both reciprocal recombination and gene conversion, the latter was predominant when the bacterial colonies containing recombinants were evaluated. Unlike mammals, NHEJ-mediated DSB repair was undetectable in P. monodon. However, we could detect evidence for an alternative mode of NHEJ that uses microhomology, termed as microhomology-mediated end joining (MMEJ). Interestingly, unlike HR, MMEJ was predominant at lower temperatures. Therefore, the results suggest that, while HR is major DSB repair pathway in shrimp, MMEJ also plays a role in ensuring the continuity and stability of the genome.

Tissue specific expression profile of some immune related genes in Labeo rohita to Edwardsiella tarda infection

Rohu (Labeo rohita), an Indian Major Carp (IMC) is an economically important aquaculture species in India. Inspite of the technological advances, infectious diseases caused by viruses, bacteria and parasites have been a major limiting factor in the development and profitability of fish farms. At present, information regarding the immune status of the Indian major carps is limited. This lack of knowledge is a major impediment for establishment of effective preventive measures against broad spectrum of infectious agents. The present study was undertaken to examine the modulation of few immune-regulatory genes: IgHC, NOD 1, TLR 22, iNOS and IL-1β during experimental infection of E. tarda in L. rohita to understand their role in pathogenesis. Rohu fingerlings were intra-peritoneally injected with Edwardsiella tarda (LD₅₀ dose of 8.7 × 10⁴ CFU/fish) and sampled for three immunologically important organs (kidney, liver and spleen) at different time intervals (zero hour or pre-challenge and 6 h, 12 h, 24 h, 48 h and 96 h post challenge). For absolute quantification of genes by real time RT-PCR, all the genes transcript were amplified from Poly I:C induced rohu lymphocytes and cloned in pTZ57R/T plasmid. Standard curves for each gene was generated from serially diluted plasmid bearing respective genes. Evaluation of copy number of different genes present in the tissue showed that the expression of IgHC, iNOS and IL-1β was highest in kidney followed by spleen and least in liver. While for NOD 1 and TLR 22 gene, liver showed higher expression than kidney and spleen. Further, the expression of IgHC, INOS, TLR 22, NOD 1 and IL-1β genes significantly differed (P < 0.05) in the E. tarda challenged fish when compared with pre-challenged control fish. Among the five genes we studied, the basal expression of TLR 22 gene was highest. The result also depicts that iNOS and NOD 1 are immediate responsive genes as their expression reached maximum level at 6-24 h post infection (hpi) after which the expression declined. In contrast, TLR 22 and IgHC gene transcript showed enhanced expression during the late phase of with maximum expression observed after 48 hpi and 96 hpi respectively. IL-1β, being the exception, showed high expression both at 24 hpi and 96 hpi. From this study, we conclude that these five immune genes have a definite role to play in the defense mechanism of host (L. rohita) against E. tarda.

Policy content and stakeholder network analysis for infant and young child feeding in India

Background

Over the last decade, infant and young child feeding (IYCF) indicators in India have improved. However, poor IYCF practices are still apparent, associated with pervasive high rates of child under-nutrition. Interventions to improve IYCF need augmentation by appropriate policy support to consolidate gains. The aim of this study was to identify opportunities to strengthen and support IYCF policies through a policy content and stakeholder network analysis.

Methods

IYCF policies and guidelines were systematically mapped and coded using predetermined themes. Six ‘net-map’ group interviews were conducted for stakeholder analysis with data analyzed using ORA (organizational risk analyzer, copyright Carley, Carnegie Mellon University) software. The study was carried out at a national level and in the states of Maharashtra and unified Andhra Pradesh.

Results

Thirty relevant policy documents were identified. Support for IYCF was clearly apparent and was actioned within sectoral policies and strategic plans. We identified support for provision of information to mothers and caregivers in both sectoral and high-level/strategic policy documents. At a sectoral level, there was support for training health care workers and for enabling mothers to access IYCF. Opportunities to strengthen policy included expanding coverage and translating policy goals into implementation level documents.

At the national level, Ministry of Women and Child Development [MoWCD], Ministry of Health and Family Welfare [MoHFW] and the Prime Minister’s Nutrition Council [PMNC] were the most influential actors in providing technical support while MoHFW, MoWCD, and Bill Melinda Gates Foundation were the most influential actors in providing funding and were therefore influential stakeholders in shaping IYCF policies and programs.

Conclusion

We identified a wide range of strengths in the IYCF policy environment in India and also opportunities for improvement. One key strength is the integration of IYCF policies into a range of agendas and guidelines related to health and child development service delivery at the national and state level. However, the lack of a specific national policy on IYCF means that there is no formal mechanism for review and monitoring implementation across sectors and jurisdictions. Another opportunity identified is the development of IYCF policy guidelines in emergencies and for tribal populations.

Aceclofenac: Species-Dependent Metabolism and Newer Paradigm Shift from Oral to Non-oral Delivery

Non-steroidal anti-inflammatory drugs (NSAIDs) are the group of drugs prescribed in various pain related disorders and inflammatory conditions. Diclofenac (DI) is widely prescribed drug for chronic inflammatory conditions like osteoarthritis (OA), a highly prevalent musculoskeletal disorder of adults, projected to affect about 60 million people of total world population by 2020. The chronic oral administration of diclofenac is linked with many gastrointestinal complications like ulceration, bleeding and perforation. These issues paved the way for the development of a structurally similar drug Aceclofenac, which proved to be a safer and more efficient alternative. In spite of better tolerability of Aceclofenac, the oral use of it is not completely free from typical NSAID like side effects. Thus in this context, it becomes mandatory to explore the potential of newer delivery approaches. Amongst the varied newer carrier-systems, microemulsion systems, lipidic colloidal carrier systems and many other supramolecular systems promise to improve the delivery. They tend to place the molecules to the desired target site or in the vicinity without disturbing the unaffected normal surrounding tissues and also ensure enhanced permeation into the skin. The current investigation highlights and deals with the different conventional and novel approaches used thus far in oral delivery of Aceclofenac, their limitations and recent shift towards non oral routes.

Delay in the Provision of Antiretroviral Therapy to HIV-infected TB Patients in Nigeria

Background

Nigeria has a high burden of HIV and tuberculosis (TB). To reduce TB-associated morbidity and mortality, the World Health Organization recommends that HIV-positive TB patients receive antiretroviral therapy (ART) within eight weeks of TB treatment initiation, or within two weeks if profoundly immunosuppressed (CD4<50 cell/μL).

Methods

TB and HIV clinical records from facilities in two Nigerian states between October 1^st, 2012 and September 30^th, 2013 were retrospectively reviewed to assess uptake and timing of ART initiation among HIV-positive TB patients. Healthcare workers were qualitatively interviewed to assess TB/HIV knowledge and barriers to timely ART.

Results

Data were abstracted from 4,810 TB patient records, of which 1,249 (26.0%) had HIV-positive or unknown HIV status documented, and the 574 (45.9%) HIV-positive TB patients were evaluated for timing of ART uptake relative to TB treatment. Among 484 (84.3%) HIV-positive TB patients not already on ART, 256 (52.9%, 95% CI: 45.0-60.8) were not initiated on ART during six months of TB treatment. 30.0% of 273 patients with a known CD4≥50cells/μL started ART within eight weeks, and 14.8% of 54 patients with a known CD4<50cells/μL started within the recommended two weeks. Only 42% of health workers interviewed reported knowing to interpret guidelines on when to initiate ART in HIV-positive TB patients based on CD4 cell count results. CD4 cell count significantly predicted timely ART uptake.

Conclusion

A large proportion of HIV-positive TB patients were not initiated on ART early or even at all during TB treatment. Retraining of staff, and interventions to strengthen referral systems should be implemented to ensure timely provision of ART among HIV-positive TB patients in Nigeria.

Within-subject covariation between depression- and anxiety-related affect

Studies find a strong positive relationship between the affective components of anxiety and depression. However, most research thus far has examined the between-person correlations among these constructs, while ignoring how changes in these two types of affect covary over time within a person. Within-person correlations could differ meaningfully from how anxiety- and depression-related affect relate across individuals. Further, individuals may differ in terms of how highly these constructs covary over time. The current study aimed to (1) compare between- and within-person correlations between anxious and depressive affect, (2) examine lagged effects between anxious and depressive affect over time, (3) test whether individuals differ in their within-person correlations between these two types of affect, and (4) examine whether the mean level of affective intensity moderated these individual differences. These questions were explored using college undergraduates (N = 50) who rated their depression- and anxiety- related affect six times a day for two weeks. A higher average correlation was observed between anxious and depressive affect in between-person compared to within-person analyses. Significant bidirectional lagged effects were observed between these constructs. Individuals with higher average levels of anxious affect experienced stronger within-person correlations between anxious and depressive affect.

Anthropometric and Nutritional Profile of People Living with HIV and AIDS in India: an Assessment

BACKGROUND

Importance of nutrition in human immunodeficiency virus (HIV) is well-established; however, the information regarding the diet quality of people living with HIV (PLHIV) especially in India is lacking.

OBJECTIVES

The objective of this study is to assess the anthropometric and nutritional profile of Indian PLHIV.

MATERIAL AND METHODS

The study was performed on 400 adult PLHIV registered at the Antiretroviral Center (ART) center in New Delhi, India. Anthropometric data including height, weight, waist, hip, mid arm, and calf circumferences, were collected; 1-day 24-h dietary recall was done to gather nutrient intake from which nutrient adequacy ratios were computed. Mini Nutritional Assessment (MNA) was also conducted.

RESULTS

The mean body mass index (BMI) of the sample was 19.73 ± 3.55 kg/m(2) with around 40% having BMI <18.5 kg/m(2) . All anthropometric measurements were found to correlate positively and significantly with CD4 count (P < 0.05). The sample consumed poor quality of diet as they could not meet even the 2/3(rd) of the Indian Council of Medical Research (2010) requirements for energy, protein, calcium, iron, riboflavin, niacin, folic acid, B12, copper, and zinc. Classification of subjects according to MNA indicated that more than 50% of the sample was at-risk of malnutrition and 34% were malnourished. With 40% of sample having BMI less than normal, 50% at risk of malnutrition together with poor nutrient intakes over a long period of time could contribute to further worsening of the nutritional status.

CONCLUSION

There is a need to develop a database on nutritional profile of PLHIV in India which reinforces the need for development of effective strategies to improve their nutritional status.

Leucocyte complement receptor 1 (CR1/CD35) transcript and its correlation with the clinical disease activity in rheumatoid arthritis patients

In view of the exaggerated complement activation in rheumatoid arthritis (RA) and significance of complement receptor 1 (CR1/CD35) as a complement regulatory protein (CRP), we aimed to determine the leucocyte-complement receptor 1 (L-CR1) transcript levels and the relationship of this protein with the clinical disease activity of RA patients. Sixty-six controls and 45 RA patients were enrolled. L-CR1 transcript levels were correlated with the levels of circulating immune complexes (CIC), C3, C4 and C3d in controls and patients and with disease activity score 28 (DAS28) in patients only. CIC levels were determined by polyethylene glycol (PEG) precipitation, C3 and C4 levels by nephlometry and C3d levels by enzyme-linked immunosorbent assay (ELISA). Eleven patients were recruited for follow-up of L-CR1 and DAS28 levels at weeks 0, 12 and 24. Appropriate statistical methods were used for the data analysis. L-CR1 (P < 0·01) transcript levels were decreased in patients compared to controls. L-CR1 levels correlated negatively with DAS28, CIC and C3d. DAS28 correlated positively with levels of CIC, C3 and C3d. Levels of CIC correlated positively with C3 and C3d. Levels of C3 correlated positively with C3d in patients and with C4 in both controls and patients. Levels of L-CR1 increased with decline in DAS28 scores in follow-up patients. Observations were statistically significant. Lower levels of L-CR1 transcript in patients compared to controls, their correlations with the levels of CIC, C3d and DAS28 at different time-points in RA patients suggest CR1 as a potential disease marker for RA.

Nutritional knowledge, attitude, and practices among HIV-positive individuals in India

This descriptive study investigated the nutrition-related knowledge, attitude, and practices (KAP) among people living with HIV/AIDS (PLHIV) in India. Data relating to nutritional KAP and sociodemographic profile were gathered from a sample of 400 PLHIV from New Delhi, India, using preset multiple-choice questionnaire. The knowledge on HIV/AIDS was low; nutritional knowledge was moderate as 80% of respondents could answer 4 out of 7 questions correctly. The attitude toward disease and food was positive but the application of nutritional knowledge was lacking as indicated by the moderate practice score of 8.1 +/- 2.3 out of a total score of 15. There were no significant differences in scores between genders. The PLHIV had knowledge about importance of nutrition during infection, had positive attitude toward the disease and the importance of nutrition during the course of the disease but translation of this knowledge into practice was low. Thus, there is a need for continuous interventions primarily aiming at behaviour change to convert knowledge into healthy dietary practices.

Assessment of Quality of Life of HIV-Positive People Receiving ART: An Indian Perspective

Context:

HIV/AIDS is known to affect an individual not only physically but also mentally, socially, and financially. It is a syndrome that builds a vacuum in a person affecting his/her life as a whole.

Aims:

The purpose of the present study is to evaluate the quality of life (QOL) of people living with HIV/AIDS (PLHIV) receiving ART and its association with Body mass index (BMI) and CD4 count.

Study Design:

An observational study was performed on PLHIV receiving ART in Orissa, India.

Materials and Methods:

Data on sociodemographic profile, BMI, and CD4 were gathered from 153 HIV-positive subjects. QOL was assessed using WHOQOL-HIV BREF scale.

Results:

The overall QOL score of the subjects was moderate; PLHIV with lower BMI also had poorer QOL (P<0.05). Employment affected only the social health domain of the subjects. Men reported poorer level of independence and physical health while women reported poorer social relationships and environment. All the six domains correlated significantly with the overall QOL indicated by the G-facet.

Conclusion:

Attention toward improving the nutritional status of PLHIV should be accorded high priority to ensure improvement in the overall QOL of PLHIV.
